IPADLOCK.

Specification of Letters Patent.

Patented My 12, 1921.

Application filed March 31, 1921. Serial No. 457,189.

which can be turned to either side when' opened/ One object of theinvention is to provide a heavy cast casing, which incloses themechanism of the lock, and plates on which the parts of the lock areassembled, which are detachably mounted in the casing, and side armorplates.

A further object of the invention is to improve the mechanism by whichthe shackle is held in the locked position.

A still further object of the invention is to provide means for holdingthe key guide in a stationary position.

These objects I attain in the following manner, reference being had tothe accompanying drawings, in which:

Figure 1 is a side View of my improved lock with one of the cover platesand one of the carrying plates removed, and showing the locking dogengaging the shackle;

Fig. 2 isa View, similar to Fig. 1, with the carrying plates inposition;

Fig. 8 is a view, similar to Fig. 1, showing the dog retracted and theshackle raised;

Fig. 4 is a sectional view on the line 4-4, Fig. l; V

Fig. 5 is a perspective View showing the casing of the lock;

Fig. 6 is a perspective view showing one of the cover plates;

Fig. 7 is a perspective view showing the two holding plates;

Figs. 8 and 9 are views of the shackle;

Fig. 10 is a perspective view of the dog release lever;

Fig. 11 is a perspective view of one of the series of tumblers;

Fig. 12 is a detached perspective view of the locking dog;

Fig. 13 is a detached perspective view of the key post; and

Fig. 14 is a perspective view of the key.

Referring to the drawings '1 is the casing of the lock made of castmetal of the form shown in Fig. 5, having a deep opening 2 for the longleg 4 of the shackle '3, and a socket 6 for the short leg 5 of theshackle. The front and rear of the casing are'recessed, as shown,toreceive the armor plates 7, Fig. 6, each of which has threecountersunk openings 8 through which. extend the rivets 9, which securethe plates to the casing. 10, 11 and 12 are projections in the interiorof the casing. These projections are narrower than the recessed portionsto receive the carrying plates 13 and14, which fit directly back of thearmor plates 7 as clearly shown in Fig. 4. On the plate 13 are pins 15and 16, which extend into openings in the plate 14 so that the twoplates are brought into alinement. Each of the plates is recessed at 17to clear the countersunk portions 8 of the armor or cover plates 7.

18 is a guide, Fig. 13, having a cylindrical portion 19 and an octagonalportion 20. The cylindrical portion of the key guide fits in thecylindrical opening 21 in the casing, Fig. 5, while the octagonalportion 20 fits between the two projections 11 and 12. These projectionsprevent thekey guide from turning. The key guide has a slot 22 for thereception of a key of the type illustrated in Fig. 14, in the presentinstance.

The pin 15 is the pivot pin for the locking dog 23, Fig. 12, which hastwo arms 24 connected by a locking member 25, which enters the notch 26in the long leg 4 of the shackle '3 and holds the shackle in the lockedposi in the tumblers 31, when the notches of the tumblers are broughtinto alinement. tumblers 31 are mounted in the pivot pins 16 and eachtumbler has a spring 32 of the or- :dinary construction, which bearsagainst a The lug 33 on the casing. In the present instance, I haveshown six tumblers, but the number and shape of the tumblers may bevaried as desired.

It will be noticed in Fig. 10 that the portion of the dog operatinglever against which the key rests may be of difi'erent lengths, as shownat 34. The dotted lines in, ig. 1Q

denote a blank before the portion 34 is re- "duced so that b increasingor diminishing the length of t e'portion 34 a number of ke "changes canbe made. V i

he long leg 4 ofthe shackle is cut away 7 at the back, as at 35, and astop pin 36 extends through an opening 37 in the casing and through thespace at the back of the shackle. This pin limits the movement of theshackle. The shackle is cut away at 38.

to allow the shackle to turn without being interferedwith by the pin. 'Aspring 39, of the; ordinary construction, islocated at the bottom of thesocket 2 in the casing and rests in a socket in the longleg 4: of theshackleso that, when the shackle is released from the dog,the.springprojectsit to the position shownin Fig. The lower portions ofthe. plates 18 and ll bearupon the inner end ofthe'key guide, as shownin Figs.

2 and 4, locking the key guide against longitudinal movement.

I preferably stiffen the plates 13 and 14 bya series-of ribs, which, inthe presentinstance, radiate from a central projection. as

shown in Figs. 4 and 7 I alsodish the armor plates 7 as in Fig. 4.. lhus, the two plates at each side ofthe lock are materially stiffened soas to resist any hammering 'ac tion to break the lock and, as Icontemplate makingthe casing of cast steel, it will be alniostimpossible to destroy the lock by the present methods. The parts of thelock are carriedby plates 7 independently of the casing, so thattheparts can be readilyassembled, after which the armor plates are placedin pdsrt-ion and secured by rivets, or other fastenings.
